man thats a light ucd60!!!! no its 7.3 lol. and you dont need a pump but you can use a cline regulator which is pretty simple and works really well and really improves the 3d effects.but no matter what this is a great plane. i nosedived my first straight into a rock garden but somehow my saito 100 and electronics survived so i just got another and im flying it now. have fun!!!
